e .it known that we, PARKER Cool: and WILLIAM E. WINE, both citizens ofthe United States, 'PABKER Cook residingV at 5 Washington, District ofColumbia, and IL- .Lnur E. W'INE residing atToledo, State of Ohio, haveinvented certain new and useful Improvements in Tank- Siphons, of whichthe followin is a specification.

Our invention. re ates to new and useful improvements in siphon valvesand especially to an arrangement for emptying tank cars.

As is well known the -general practice is to provide a tank car with avalve at the bottom thereof and to empty the tank by gravity, that isprovide a valve at the bottom of the car which is operated from the Ito}; thereof after the dome cover is open.

here are however many objectlons to the present form of valves employedat the bot- .tom of the tank car, for the reason that in a number ofinstances the valve has become jammed 01]? its seat, which resulted inthe loss of the entire amount of gasolene in.

the tank car and onseveral occasions resultinfg in greatproperty lossand also loss of One of the objects of our invention therefore is toprovide a valve mechanism whereby the tank is emptied by a siphonarrange ment, and wherein it will be impossible for the car in.transitto berelieved of its load of oil, or gasolene, or other fluiduntil a vacuum is first formed andwhich vacuum has to bestarted by amanual operation.

'Another object" of our invention is to provide a valve arrangementwhereby the flow of gasolene or oil from the tank cannot be starteduntil the dome cover is opened, thus avoiding anyaccidental flow ordischarge of the contents. of the tank until desired; and also toprovide an arran ement whereby if for any reason it is desired to stopthe flow'or discharge of the tank, it is simply necemary ,to destroy thevacuum 1n the improved valve arrangement to be hereinafter fullydescribed.

Still another object of our invention is to provide a. siphon valvearrangement for tank cars whereby there is no vacuum in the valve arranment when-the dome cover is closed there y preventing any accidentaldischarge of the contentsofthe tank.

Specification 9 Letter! Intent Patented June 12 1917.

Application filed July 7, 1816. Serial No. 107,951.

Still another object of our invention is to provlde a tank car with theimproved discharge arran started, and t at may be easily stopped by thebreaking of avacflum, and wherein it Wlll be impossible for any loss ofthe con.- tents of the tank car unless the carshould happen-to bedamaged by a wreck, etc.

Still other ob'ects of our invention are toprovide asip on arrangementthat may be-quickly and: readily installed in the tank car s now ingeneral use, or that 'may be quickly and easily provided in any formsof' new tank cars and at the same time complyv with all the requirementsset out by the Master Car Builders Association.

With these and other objects in view our invention consists in certainnew and useful improvementsand combination of parts as will behereinafter more fully describedand pointed out inlth'e claims.

In the drawings Figure 1 1s a vertical ment that may be easily' sectionof the improved tank siphon arrangement.

Fig. 7 is an enlarged detail sectional view of the valve located at theupper part of the siphon and showing in dotted lines the valve in itsclosed posltion.

Referring now to the drawings -A dome 1 of the ordinary form 'used ontank cars is shown-having an opening and a cover 2 at the 'top thereof.It is to be "nderstood' that the form of dome or tank car form no partof the invention and thehereinafter described arrangement may besuccessfully'used with any of the general. forms now inuse.

Secured preferably centrally to the bottom of the tank is a casting 3which will be hereinafter termed the base member? and as will be seen isriveted as at 4 after-a portion hasbeen out out of-t'he bottom of thetank, the said cutout portion being of nearly I the same diameter of thebase member.

This base member 3 is preferably a unitary casting having the flange 5at the upper ortion thereof WlllCl'l flange is riveted as'beorementioned to the bottom of the tank car. In the bottom of this basemember 3 is the discharge opening 6, which is extended and the outerportion is shown as threaded externally as at 7 for the receptlon ofacap or nipple, so that a further discharge pipe may be secured thereto.Shghtly above the threaded portion 6, the base member widens at one sideso that a valve 8 may be pivoted as at 9, which valve is operated by thetappet or stem 10, the lower portion of'whlch extends through theopening 11 in the base member 3 and the lower portion of said stem 10normally'forcing' the outer end 12 of the valve 8 downwardly and therebyforcing the closing portion 13 of the valve against the valve seat 14formed centrally of the base member 3.

The'said base member 3 has as shown a centrally located verticallyextendin tubular portion 15, which tubular portion exte'nds above thelevel of the sides of the base member 3. vThis member is preferably castintegral with the base member and is imperforate at its bottom or inother words if so arranged that it is not possible for any fluid thatcomes within the base member to get withinthe said tubular portion 15excepting that it pass up through the top member and down into thetubular portion 15 which action will be hereinafter described;

This tubular portion 15, is preferably internally threaded as at 16, andsecured therein isthe pipe 17, the lower end ofwhich is externallythreaded as at 18, and the upper end of which is designed to extendabove the fluid level of the tank.

Referring for the moment again to the base member 3, it is to be noticedthat the 7 central tubular portion 15 is also provided on its outersurface with four guide members 19 which members tend to strengthen thecentral member 15 and also to guide a casing 20 in itsupward anddownward movement. A

This casing 20 as will be noticed is preferably threaded at. its upperend as at 21 to fit withinwhat I term the cap member 22, which capmember is internally threaded at its lower portion as at 23, and saidcap and casing inc'loses the pipe 17, but the said casing 20. is open atits lower end.

' It will. be remembered that the pipe 17 is threaded at its lower endto he member 15,'and that the casing 20 is threaded tothe cap member-22at its upper end, so that any variance in sizes of the difierent tankcars maybe easil .met, all that it is necessary to change, if t e carsare of difierent height,

being thelengths of the pipe 17 and cas- 4 dteferring now to the capmember 22, it

or guide member 28, which is secured to the inner surface of the dome,as at 29, this guide member 28 securely holding the cap member 22 in analined vertical position; also by providing the shoulders 27 asmentioned it is impossible to raise the said cap member 22 and thecasing 20 connected thereto above the position as shown in Fig. 2.

By using this member 28, the inner guide members 25 in the cap portion22, and the lower guide members, a very rigid construction is obtainedwhich of course is de sirable in an article of this kind.

A further brace member 30 is shown the ends of which member are fastenedto the member 28 and which member partly surrounds the cap member22 andis also provided with a flanged portion 31 through which passes theupper end of the aforementioned stem 10. This stem has provided near itsupper end and directly beneath the flange member 31 a spring 32, whichis held in place by the stop or washer 33. Atthe upper end of this stemis a handle 34 which .is irregularly shaped, and said stem is normallyheld by the spring 32 in its downward position to normally hold thelower valve in its closed position. A movement of the handle 34 at thetop of the stem 10 however will draw' the stem 10 upwardly thus allowingthe lower valve 8 to open.

Referring again to the top casing 22 it will be seen that in its upperend is the opening 35 in which opening there is secured a valve 36 whichvalve, is provided with a handle 37 and it is to be especially noticedthat when this handle 37 is in itsup'ward position the valve is closed,and when the handle sis in its downward position, the valve'is open.

In other words itis impossible to close.

the cover 2- unless the handle 37 is pushed downwardly and the valve isthen and must be, in its open position.

A description of the operation of our ini 20 up to the normal levelsimple to break the oil or handle 24 and 'pull upwardl' on the same.

thereby lifting the cap 22 an the casing 20 upwardly until the shoulder27 comes in contact with the brace and guide member a 28. As the uppervalve member 26 is closed, and as the lower valve member 8 is alsonormally closed, the upward movement of the ca 22 and the casing 20,will form a partia vacuum in the pipe- 17 and in the top. of the cap 22,which vacuum will pull \solene up in the space between the pipe I? andcasing 20 into the top cap and it will then flow nto the pipe 17.

The operator will then grasp the handle 34 and open the lower va vs 8and the oil will then flow out of thepipe 17, thus start ing the siphonand will in this manner discharge the entire contents of the car. Whenthe operatorreleases the upper handle 24, the top cap and casing 20 willof course lower themselves but will in no way efl'ect the si honarrangement. If for any reason it is esired to cut off the flow ofasolene, it will be only necessar to open t e valve 36 at the top whichwou d break the vacuum in the ca and in the inner pipe 17 and the flowwould of course instantly stop. Also the valve 8 might be operated tclose the flow at the bottom but it is just as the vacuum as abovementioned.

It is to be noticed that when the car is in transit and the dome coverlocked down,

the valve 36 will be open and even' should the valve 8 becomedisarrariiged cr jammed orin any manner forced 0 its seat, there will beabsolutely no loss of the contents of the car as to et into this innerpipe 17 it A is necessary t at the cap 22 be manually lifted and thatthe up er valve be closed which cannot happen 5 the dome cover beclosed.

From the above it will therefore be seen that with our improvedarrangement it is impossible for the loss of the contents of the carunless the entire bottom casing was ripped ofl of the car and evenshould the bottom valve become jammed or held open still no 10$ ofgasolene can occur, at the same time the arrangement is such that theflow may be easily and quickly started, or as easily discontinued asbefore described.

Mere colorable changes may be made without departing from the spirit andscope of the invention.
